摘要
介绍UC3842工作特性,并设计一种单端反激式、具有多路输出功能的开关电源。详细介绍电源各部分的设计原理及参数的确定,结合UC3842芯片的优点,制作样机。目前该电源已用于变频器内部功能模块供电,实验证明性能稳定可靠,满足设计要求。
The characteristic of the UC3842 was introduced in the paper,and design a single-end fly-back switching power supply,it has multi-output function.The design principle and parameter determination of power all parts was described in detail.Combines the advantages of the chip of UC3842,and developed the prototype.At present,the power has used in the inverter for supplying function modules.The experiments proved that the performance is stable and trustiness,also meet the design requirement.
